Subject: [PATCH] firewire: sbp2: replace a GFP_ATOMIC allocation
Date: Sun, 4 Mar 2012 14:23:00 +0100 [thread overview]
Message-ID: <20120304142300.560717a1@stein> (raw)
sbp2_send_management_orb() is called by sbp2_login, sbp2_reconnect, and
sbp2_remove, all which are able to sleep during memory allocations.
Actually, sbp2_send_management_orb() itself is a sleeping function.
Login and remove could allocate with GFP_KERNEL but reconnect needs
GFP_NOIO to ensure progress in low memory situations.
